Printer Object won't persist

Tech-Archive recommends: Speed Up your PC by fixing your registry

I have a simple report that I would like my user to be able to assign a
printer to. I followed the example in
http://msdn.microsoft.com/en-us/library/bb258178.aspx and downloaded the DB.
The task seemed straightforward, but could not get my report to remember its
newly assigned printer. After several days of trial and error, I finally
noticed that the example DB does not have any code associated with some of
its reports (HasModule=No). My report does so I set that property to No for
testing and it works??? I then returned to the sample demo and sure enough it
doesn't work either if any report has any code linked to it.
Can anyone please explain, I need code behind my report?
Thanks!
